Abstract: 561,122. Viscosity regulators. AKTIEBOLAGET AEROTRANSPORT. Nov. 30, 1942, No. 17026. Convention date, Nov. 29, 1941. [Class 135] A viscosity regulator is controlled or actuated by a differential piston or the equivalent moved in one direction by the pressure difference across a friction channel and in the opposite direction by the pressure difference across an apertured plate or the equivalent in series with the friction channel, the parts being so proportioned that the effect of variations of pressure drop in the friction channel occasioned by variations in the velocity of the medium is cancelled out. In the arrangement shown diagrammatically in Fig. 1, engine lubricating oil entering at 1 passes through an apertured plate 4 and friction passage 3 and escapes in part through a passage 8 leading to an oil cooler and in part through a pipe 9 to a point in the lubricating system beyond the cooler under the control of a differential spring-loaded piston 5, 6. The outer face of the piston 6 is subject through a pipe 11 to inlet pressure, while the outer face of the piston 5 is subject to the pressure existing between the restrictions 3, 4. Both the inner faces are subject to the pressure on the outlet side of the constriction 3. In the arrangement shown in Fig. 2, the main valve (not shown) is actuated by a servomotor under the control of a piston valve 37 which is operated to connect a passage 39 leading to the servomotor either to an exhaust connection 41 or to the main oil inlet 16.by way of chamber 33 and passages 36, 42 in the valve member. A spring 32 normally holds the valve against the lower end of a tubular spindle 29 secured to a differential piston 27. The piston 27 is provided with restricting apertures 28 and works in a fitting 22 secured in an outer casing 15. The friction channel is formed by a number of tubes 26 inserted in a tubular member 25 screwed in the lower end of the fitting 22. A cylindrical filter is arranged between the fitting 22 and the lower part of the casing. In a modification, the friction passage is formed by arranging concentric cylinders in the member 25 and the valve 37 is replaced by a lift valve which controls the supply of oil to a pipe fitted with a bleed-port and connected to the servomotor.

Title: Mechanically operating retarding device for projectile fuses
IPC: F42C1/04
Filed: 1926-07-12
Abstract: 255,108. Remondy, L. E. July 11, 1925, [Convention date]. Projectile fuzes.- A direct-action striker C<1> or other member of a fuze is locked at safe by balls D situated between a cylindrical wall e and a conical face c, and preferably held in place by a spring G. The striker thus locked can be released by an inward pressure thereon only when accompanied by a rotation of the striker, for example by wind-vanes F. The balls then travel in a helicoidal path until they escape into an enlarged recess E<1>. The striker is then free to be driven against the percussion cap B on impact, but may be held until then by a shear-wire H. This device may be made to act as a time fuze, the striker being thrust by a spring against the percussion cap when the balls escape from the conical clutch. The functions of the striker and percussion cap carrier may be reversed, and various other modifications of detail may be made. A similar ball clutch may be used to release a safety cover from a fuze. In some modifications, the direct-action striker is provided with a safety collar adapted to be released before or automatically on discharge, and the percussion cap is cushioned by a spring as an additional safety, so that firing cannot take place by the approach of the striker against the cap unless the cap is simultaneously subject to momentum. The Specification as open to inspection under Sect. 91 (3) (a) also describes a modification in which the ball clutch is replaced by a screw- and-nut device. This subject-matter does not appear in the Specification as accepted.
